Description
Technical field
The present invention relates to a kind of by claim 1 connector arrangement that is used for pipeline and flexible pipe with material cross-section of reinforcement as described in the preamble.
Background technique
For example EP 0 750 152 B1 by same claimant are known for a kind of such connector arrangement.The full content of this document should be contained in the disclosure of the present invention.
In this known connector arrangement, connector device (Stecker) by cover in one with it the overcoat of parallel sensing constitute, respectively be enclosed within the zone of seal ring and interconnect.Between these two covers, constitute a receiving cavity that is used to insert a flexible pipe.The connector device has constituted double-walled in the zone of seal ring in this known enforcement.
Verified now, connector arrangement need be accepted high relatively connector power, and must be especially spring clip and with the zone of the opposed kayser convex shoulder of spring clip in accept axial tension.
In EP 0 750 151 B1, the kayser convex shoulder is connected with a spring clip through hole in taking over the zone in this is formed in the overcoat zone of single wall.
But dangerous when high Separating force affacts on the connector arrangement, promptly the spring clip through hole of connector device side ruptures in the overcoat zone, therefore has the danger of connector arrangement release.
Summary of the invention
Therefore task of the present invention is, further develops the connector arrangement of the described type of beginning, makes it can accept obviously higher fastening force.
In order to solve the task of proposition, the invention is characterized in that the connector device is formation double-walled in the zone of spring clip through hole at least.
Set in a kind of further expansion of the present invention, the described double-walled that is arranged at least in this zone has a less toward each other distance and directed in parallel to each other.
In the described a kind of preferred structure that is arranged on the double-walled in the spring clip via regions at least, usually preferably, double-walled in the zone of through hole, squeeze close (zusammenquetschen) and outside via regions, have a bigger toward each other distance, there extend abreast and by one radially the end wall of orientation interconnect.Technology instruction by providing obtains following advantage: the spring clip through hole is that material is strengthened, and is parallel to each other directed and has the double-walled of small distance toward each other because the interior cover of connector device and overcoat squeeze to merge and constitute at least in this zone.
Xiang Guan other advantages are therewith, are arranged on the receiving cavity that inserts flexible pipe that is applicable to that the interior double-walled of spring clip via regions in axial direction is extended to a corresponding annular backwards.
Though this special flexible pipe receiving cavity EP 0 750 152 B1 by oneself is known, this receiving cavity is not the cross section formation by double-walled up, but only passes through the parallel position formation of interior cover and overcoat.
By the present invention, the receiving cavity that is used for flexible pipe is crimping and squeeze and close forward, and this obvious higher intensity (Spreizfestigkeit) that struts with receiving cavity is relevant.
Therefore with respect to the theme of comparable EP 0 750 152 B1, this receiving cavity prevents radial dilatation better or struts.
In this document, be enclosed within outward on the excircle that abuts in flexible pipe in the zone of spring clip through hole and by its supporting.Keep and produce certain support effect.
Therefore but in the present invention, the spring clip through hole is not cantilevered (freitragend) and advantageously constitute double-walled.This is relevant with following advantage, promptly obtains high rigidity with relatively thin material cross-section in the zone of spring clip through hole, is not this situation in EP 0 750 152 B1.Must use relatively large material cross-section to form the kayser convex shoulder there.Especially the zone of spring clip through hole must be designed to particularly material reinforcement on taking over and on the connector device, and this is relevant with high manufacturing cost.
Use the present invention at this, it obtains superior intensity by obvious thinner material cross-section in the spring clip via regions, therefore produces the higher fastening force of connector arrangement under the situation of materials with smaller cross section.
Other advantages of the double-walled of connector arrangement in the spring clip via regions are, the connector device constitutes double-walled by the present invention on the end face of its front, therefore do not form sharp-pointed cutting seamed edge and injury seamed edge, in EP 0 750 152 B1, perhaps be this situation for example, because simple there highly crooked (hochgebogen) seamed edge has corresponding risk of injury.
Subject matter of the present invention not only results from the theme of each single claim, and results from the combination of each single claim.
All are disclosed explanation and feature except that summary hereof, and the spatial structure that especially is described in the drawings is claimed as invention essence, as long as they are new with respect to prior art either alone or in combination.
Description of drawings
Explain the present invention in detail by means of the accompanying drawing that a kind of mode of execution only is shown below.Obtain important feature and advantage of the present invention at this from the description that accompanying drawing reaches accompanying drawing.Wherein:
Fig. 1 presses the phantom of connector arrangement of the present invention,
Fig. 2 is along the front view of the connector arrangement of direction of arrow II among Fig. 1,
Fig. 3 presses the side view of perspective of the connector arrangement of Fig. 1 and 2.
Embodiment
Press Fig. 1, one for example by metal or be inserted in the connector device 7 and kayser there by the adapter 1 that plastic materials is made.
Take over 1 and mainly constitute, kayser convex shoulder 2 of moulding on the excircle of cover by a columniform cover.Kayser convex shoulder 2 is along the inclined-plane 3 of a front of connector direction formation, and it carries out the transition to a kayser face 4 backwards.
With the following realization of the kayser of connector device 7, promptly connector device 7 with one roughly the spring clip 9 that forms position, three different cards lock sections generally of U-shaped be connected.
The latch arm that is arranged in parallel 10 by U-shaped spring clip 9 constitutes two mutual opposed kaysers.
The spring clip through hole 8 that is parallel to each other on the connector device 7 is passed in latch arm 10 interlockings of spring clip 9.The spring end 11 that bends outwards of moulding respectively on the front end freely of latch arm 10.
5 formations are bent by a kayser in the 3rd middle kayser position, and the inclined-plane 3 of the kayser convex shoulder 2 that this kayser bow interlocking is passed one on the connector device 7 kayser bow through hole 6 of attaching troops to a unit and faced toward adapter 1 points to and snaps in the back on this inclined-plane.
The sealing of plug-in connector obtains by a seal ring 12 that is assemblied in the connector device 7, and the sealing ring abuts on the inclined-plane 3 of kayser convex shoulder 2 hermetically with its sealing lip 13 that points to down that tilts.By the present invention, connector device 7 comprises the interior cover 14 that a substantial axial is pointed to, and cover is configured for the interior continuing surface of flexible pipe 16 in this.In cover 14 carry out the transition to a flange 18 along the connector direction, this flange constitutes a receiving cavity that is used to hold the basic arm (Basisschenkel) of seal ring 12.
The receiving cavity that is used for this basis arm limits by a columniform supporting surface 19 of interior cover 14 up, and this supporting surface itself carries out the transition to the double-walled 21 that in axial direction is positioned at the front via an inclined-plane 20.
Intermediate cavity between interior cover and overcoat 14,15 is used as the receiving cavity of flexible pipe 16, and this flexible pipe is pushed into the backstop limit 17 on the receiving cavity that is used for seal ring 12 always and abuts in the there.
For control flexible pipe 16 whether be pushed into far enough in the receiving cavity between cover and the overcoat 14,15, overcoat 15 has on diameter the peep hole 22 that distributes and be provided with, and passes peep hole and can see hose material.
Now importantly, double-walled 21 is crowded closing in the zone of kayser bow through hole 6, as described at the front view of Fig. 2.Double-walled 21 is via connecting interior cover and the overcoat 14,15 that transition region 23 thereon is extended in parallel to each other and is provided with spaced relative to each otherly in the side, this zone connects by an end wall 24.
In the zone of the spring clip through hole 8 that is used for latch arm 10, end wall 24 is reduced to one via transition region 25 again and squeezes the double-walled 26 that closes, and it only is present in this moulding for the length of spring clip through hole 8.And then transition region 25 is arranged again, and it carries out the transition to larger area end wall 24.
Double-walled (having double-walled 21 and 26) is not only on the right side of corresponding spring clip through hole 6,8, and in its left side, for example draws by the flange among Fig. 1 and 2 27.This flange constitutes interior interior cover in through hole 6,8 zones and the transition region between the overcoat.
The narrow cross-section of given for this reason double-walled 26, therefore it be (the last ü bertragend) of special highland transmitted load because interior cover and overcoat 14,15 in this zone especially closely and transmitted load ground recline mutually.
Therefore with respect to old invention EP 0 750 152 B1 of oneself, the material cross-section of making the original plate of connector device 7 can reduce 60% and obviously improve the fastening force of connector arrangement.
Self-evident, described connector arrangement also can be made and connector device 7 can constitute the working of plastics of a material one with flexible pipe 16 by a kind of working of plastics by its double-walled.
So connector device 7 needn't be formed by the metalwork deep-draw.It also can be made with injection moulding.
